A photographic printer has an exposure station, in which a frame of a photographic film and color photographic paper are set. A light source is disposed in opposition to the color paper with reference to the photographic film set in the exposure station, and constituted by LED elements. The LED elements are disposed in a matrix for emitting light of red, green and blue colors. The light source illuminates the frame from behind. The color paper is exposed by the light transmitted through the frame, to print the frame recorded on the photographic film to the color paper. In a preferred embodiment, a drive signal is determined individually for driving respective the LED elements. The drive signal is applied to the respective LED elements.
